Pollution
Degree
Description
1 No pollution or only dry non-conductive pollution occurs. The pollution has no influence.
2 Normally only non-conductive pollution occurs. Occasionally a temporary conductivity, caused by
condensation, is expected when the drive is out of operation.
3 Conductive pollution or dry non-conductive pollution occurs, which becomes conductive due to
condensation, and is expected.
4 The pollution generates persistent conductivity caused, for example, by conductive dust, rain, or snow.
